If you go out but don’t have anything to keep food cold, you often wonder how to build a refrigerator to keep food cold without using electricity? You are lucky if you read this article to the end.
Here, Publican Anker will guide you to make a makeshift refrigerator that can keep cold without plugging in. It’s hard to believe. Watch until the end of the tutorial to satisfy all your curiosity.
How to Build Your Own Refrigerator
The idea of building your refrigerator is becoming more attractive as the price of new kitchen appliances continues rising.
This process can be more difficult than buying a new refrigerator. However, it can also be cheaper and more efficient. Reusing parts from older refrigerators to build the new one will allow you to keep recyclable waste out of landfills.
To find a refrigerator that is not in working order, check secondhand shops, junk shops, and classified ads sections of your local newspaper.
It doesn’t matter if the vehicle’s condition is in good shape, as you will be driving it. You can also leave them outside in bad condition, as you will only be salvaging the interior storage compartment.
You will need to remove the refrigerator doors to access the air conditioning components. Once the doors have been removed, locate and remove the wire that activates your door light. This will allow you to reuse it. Take out all fans, wires, and mechanical components.
The compressor, the evaporator, and any dehumidifiers are all included in this group. Take out all these components from the junk refrigerator.
Take the freezer out of the refrigerator. A chest freezer is cheaper and has more space. It’s just not practical to keep a freezer in a home refrigerator.
You can use chalk to trace a line around the fridge, just above the storage compartment. To completely remove the freezer compartment, use a circular saw. You will need to cut through the outer skin, insulation, and interior surface.
Make a platform frame to support your refrigerator. To build a platform, use 2-by-4-inch studs. Then raise the bottom 12 inches from the floor with the studs. This gives the refrigerator more space below and makes it more comfortable.
To prevent cool air from getting through your refrigerator’s bottom, add two sheets of foam insulation to the frame.
All sides of the storage container should be covered with foam insulation. Spray adhesive or hot glue gun can be used to attach sheets of foam insulation to all sides of your storage box, including the top.
Make sure to get the wire from the door light back and run it through insulation. This wire will be connected to the power supply in a later step. Now your storage box can be converted into a refrigerator unit.
Get the necessary parts to cool the air in your storage container. You will need a compressor, evaporator, and some thermostat control.
The Danfoss BD-50 is the most efficient compressor. This compressor can be used in a variety of DC-powered refrigeration kits. A Super Cold Machine or similar starter kit can be ordered from R Parts Refrigeration Parts Solutions or any other marine supply store (see Resources).
You will need to find a location where you can set up the condensing units for your refrigerator. It should be in a well-ventilated area. It should be placed away from the fridge if possible.
You can mount the condensing unit into the basement rafters if you have a basement.
The thermostat and evaporator should be installed inside the storage compartment. You will need a drill bit measuring 1 1/2 inches to drill a hole through the insulation foam installed on the box’s outside. The ideal is to drill a hole in the box’s upper right or upper left corners.
Attach the evaporator tube to the refrigerator by pushing it into the hole at the back.
You can do this by placing the tube on top of the port on your evaporator and then tightening it with a screw clamp. Mount the thermostat on the evaporator, and then plug it into the thermostat. Seal the hole with putty when you are done.
Connect the condensing device to the evaporator. Ensure the tube you connected to the evaporator during the previous step is long enough to reach the condensing unit. Connect this tube to your unit according to manufacturer instructions.
You can do this by first sliding the tube over the receiving port and then tightening the screw clamp to hold it in place.
Connect the power supply. Your evaporator, thermostat, and other components will all come with a fuse power supply. The power supply connects your condenser and evaporator to form a DC power unit. It can use either 12 volts, 24 volts, or both.
The power supply can then be connected to a standard vehicle battery. This can be changed manually with a charger or set up to automatically recharge using solar energy (see Resources below).
A wood veneer can be added to the refrigerator. Even though the refrigerator can be used with only foam insulation, it will still function well. However, it will look better if you add a veneer face to it. To give your refrigerator an appealing exterior, you can use 1/4-inch oak plywood.
Use a construction adhesive like liquid nails to attach the plywood sheets onto the fridge’s exterior. Before installing the plywood, you may want to stain it or varnish it.
How To Make A Natural Refrigerator?
Natural Refrigerator with Easy to Find Materials
This shouldn’t seem too difficult if you already knew the basics of evaporation when you were in school. It is based on one simple principle: evaporation causes cooling effects. This is quite obvious if you stop and think about it. Recall the last time you were in contact with the clinical spirit.
It evaporates faster than water because of its lower boiling point. This leaves behind the cooling effect that we are referring to. Pour some on your skin, and watch the cooling effect. As the liquid evaporates, you should feel a cool sensation. If you don’t feel this, then you are probably an alien.
We will now use a paint bucket to make this natural refrigerator.
This bucket will be our outermost layer. You can use any color and size you like. Make sure that you have a clay container that will fit in the bucket. The bucket is then filled with sand until it is quarter full.
This will explain the science at the end. The clay pot that we have chosen will be placed inside the bucket.
Continue to add more sand to the bucket until the clay pot has been completely submerged. Make sure there is no sand in the pot. We don’t want any of the items inside to be covered in sand.
Two towels will be needed once that’s done. The other towel will be wrapped around the pot and placed on top of any sand. It would help if you did not cover the clay pot’s top.
Next, add water to the towel. The water will slowly drain into the sand beneath it. This is what we want. You can pour water directly into the sand, or you can use a towel. We are trying to achieve gradual cooling. This would take longer if the water evaporates slowly.
Here is where you put anything that will stay fresh in the clay pot.
In the conditions described here, vegetables are the most durable. The maximum time that perishable goods can last is 24 hours. Finally, you can cover the entire bucket with a damp towel.
It was 44 degrees Celsius outside when the experiment was completed. After one hour, the temperature in the clay pot reached 26.9 degrees Celsius.
The temperature dropped to 17.3 degrees after three hours. This data shows that the temperature has been gradually dropping. This was exactly what we expected. We will need to add more water to the space once the water has dried out completely.

How Does it Work?
Evaporative cooling. It is the process whereby the clinical spirit evaporates from our hands, and we feel cold.
This is the experiment that we discussed earlier. Everything is made up of tiny molecules, even water. Water molecules vibrate during evaporation. Some molecules are broken off, and the water’s energy kinetically decreases.
In simpler terms, this is called cooling. Because water molecules are present in the sand, the effect will be felt in the clay pot. This will cause the inside of your pot to become colder and eventually the contents to cool down. It’s that simple! It’s easy to get started!
What do you need to build a fridge?
Things you’ll need:
- Junk refrigerator
- Wire cutters.
- Basic toolset.
- Circular saw.
- Boards 2-by-4 inches
- Foam insulation sheets.
Do you just plug in a refrigerator?
You may be wondering if you can lay down a refrigerator to move it. The short answer is no. It should not be stored or moved on its side. It is best not to place a refrigerator on its side during transport.
How can I make a refrigerator without electricity?
Here’s how you make it: You will need two unglazed ceramic pots, one that fits inside the other. Add a few inches of sand to the bottom of your larger pot. Place the smaller pot into the larger one. Sand should be used to fill the spaces between the pots. Add water to the sand.
How much does it cost to build a refrigerator?
Installing a built-in refrigerator is expensive. The cost of installing a built-in fridge is between $2,900 to $6,130. It includes both labor and the appliance. Built-in refrigerators are the most expensive and can be installed for as high as $130 to $3900.
This method will help you save a lot of money. It is not as good as official refrigerators, but it can provide cooling for situations where there isn’t a refrigerator or refrigerator at the time. This method can create a temporary refrigerator, but it is not as functional as a modern refrigerator.
